Index was outside the bounds of array - Problem only After Build deployed, not in local env

Hi,

Our project was built based on concept "Encapsulate Invocation", which has UI, Business Layer and Data Access Layer.

And, in one of the forms a method call ends up showing the error "Index was outside the bounds of Array". I believe this happens when Business layer tries to commuicate with Data Access Layer. This occurs only when the build is deployed, but could not be reproduced in local environment. I got no clue, as I could not even debug.

Could you please suggest what could be missing ?

Thanks,

Arjun
